Pg. 49, Troubleshooting:
Takes more than 10 minutes to get a position fix:
1. If there are any obstacles nearby or overhead, move to a new
location.
2. Make sure that the antenna is pointing up, has a clear view of the
sky and is a reasonable distance away from your body.
3. Check Satellite Status to see where the satellites are and if the
receiver is acquiring data.
4. If the receiver still does not get a position fix within 10
minutes, you may wish to repeat the initialization procedure.
For initialization, see pgs. 4 and 41.
